Description
Technical field
The present invention relates to a kind of elevator electro-magnetic braking device, the multi-thread girth sheets formula of specifically a kind of modular assembly type drg.
Background technology
Usually all be provided with brake equipment on elevator traction machine, when elevator cut off the power supply, brake equipment was braked the towing machine of traction elevator.Shortcomings such as there is complex structure in the disclosed towing machine of existing China Patent No. ZL200520015258.5 with folding brake, makes and the cost of installation height, and noise is big.And just simple two circular coils and the unresolved above-mentioned problem of mentioning of on the former basis, racetrack-type rotor coil being changed into of the board-like drg of the disclosed twin coil of China Patent No. ZL200820106008.6.Other has China Patent No. 200910100106.8 disclosed a kind of electromagnetic folding brake for tractor that the iron core of original one is divided into three parts, connect as one by bolt of rear end plate, improved the high problem of ZL200520015258.5 tooling cost to a certain extent, but it is big to fail to solve its noise, and complex structure is installed the shortcoming of adjusting trouble.
Summary of the invention
The invention solves the deficiencies in the prior art, and disclose a kind of towing machine magnet stopper, advantage such as have modular construction, difficulty of processing is little, tooling cost is low, materials are economized, assembling is simple and reliable.
The present invention takes following technical scheme: the towing machine magnet stopper, comprise armature 6, iron core 5, coil 7, iron core base 3, bolt of rear end plate 2, tie bolt 4, retarding spring 11, spring perch 12, brake facing 9, micro-switch 1, device 10 and spring 11 declutch, described armature 6 is arranged in parallel with iron core 5, and leave the gap, armature 6 is fixed on the iron core base 3 by the bolt of rear end plate 2 at two ends; Described iron core 5 is fixed on the iron core base 3 by tie bolt 4, and coil 7 is enclosed within iron core 5 outer rings and cooperates with iron core, and spring perch 12 is enclosed within coil 7 outsides, and spring perch is fixed on the iron core base 3; Described iron core 5 and coil 7 are at least two, and the bolt of rear end plate 2 at two ends oppositely is provided with mutually; Described spring 11 is positioned in the spring perch 12, and two ends head on armature 6 and iron core base 3 respectively; Described micro-switch 1 is installed on the iron core base 3, moves by the push rod bolt that is installed on armature 6.
By a plurality of iron cores and coil are set, with respect to single iron core and coil, the structure of iron core is simple relatively, reduces difficulty of processing, cost-cutting.
Spring evenly is provided with, and makes armature disperse the impulsive force of iron core base, and cushion effect is bigger, avoids armature excessive to the direct impulsive force of spring perch, helps reducing noise.
Compared with prior art, the present invention passes through optimal design, adopt two iron cores 5 or surpass two iron cores 5, adopt two coils 7 or surpass two coils 7, iron core 5 is fixed on the iron core base 3 by tie bolt 4, can make the simplified processing of iron core 5, spring 11 is installed in the spring perch 12, and spring perch 12 is by glue and being bolted on the iron core base 3.The elastomeric material that spring perch 12 adopts plastics, rubber etc. to be easy to be shaped can reduce the noise that produces because of the bump of armature 6 greatly.
Description of drawings
Fig. 1 is the structural representation of device of the present invention;
Fig. 2 installs scheme drawing behind the iron core for spring perch of the present invention;
Being labeled as in the accompanying drawing: 1-micro-switch, 2-bolt of rear end plate, 3-iron core base, 4-tie bolt, 5-iron core, 6-armature, 7-coil, 8-friction lining base, 9-friction lining, the 10-device that declutches, 11-spring, 12-spring perch, 13-spring eye.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment: as shown in Figure 1, the towing machine magnet stopper, comprise armature 6, iron core 5, coil 7, iron core base 3, bolt of rear end plate 2, tie bolt 4, retarding spring 11, spring perch 12, brake facing 9, micro-switch 1, device 10 and spring 11 declutch, described armature 6 is arranged in parallel with iron core 5, and leave the gap, armature 6 is fixed on the iron core base 3 by the bolt of rear end plate 2 at two ends; Described iron core 5 be two rounded, and be fixed on the iron core base 3 by tie bolt 4, coil 7 is enclosed within iron core 5 outer rings and cooperates with iron core, spring perch 12 is enclosed within coil 7 outsides, spring perch is fixed on the iron core base 3; The bolt of rear end plate 2 at two ends oppositely is provided with mutually; Have on the spring perch be used for mounting spring spring eye 13(referring to accompanying drawing 2), spring 11 is positioned in the spring perch 12 and rectangular distributions, two ends head on armature 6 and iron core base 3 respectively; Described micro-switch 1 is installed on the iron core base 3, moves by the push rod bolt that is installed on armature 6.Friction lining base 8 is fixed on armature 6 outsides, and friction lining 9 is fixed on the friction lining base 8.The device 10 that declutches is fixed on iron core base 3 outsides.
Principle of work of the present invention is:
After the magnet stopper energising, coil 7 produces electric field, forms magnetic field in iron core 5 and iron core base 3, makes armature 6 adhesives, and friction lining 9 and the towing machine friction disc on the armature 6 unclamps at this moment; After the outage, iron core 5 and iron core base 3 lose magnetic field, discharge armature 6 under the application force of spring, and the friction lining 9 on the armature 6 is fitted with the towing machine brake disc again, thereby towing machine is shut down.Bolt of rear end plate 2 by the adjusting two ends is gone back scalable iron core base 3, armature 6 is parallel with towing machine, to guarantee the balance of braking.
The present invention adopts twin coil 7, can effectively reduce the drg temperature rise, spring 11 is fixed on and adopts in the spring perch 13 that elastic plastics or elastomeric material make, and this spring perch 13 can reduce the noise of armature 6 bump generations a little more than iron core 5 surfaces when the drg adhesive.Whole drg adopts the module assembling design, greatly reduces the processing and manufacturing difficulty, and can economize on resources by actv..
